Change speed gear box 8 can realize two when tubing string hoists and just keep off and reversing gear with one, gear 83, gear 85 empty set are on power shaft 18, engaging sleeve 88 is between gear 83, gear 85, the left and right of engaging sleeve 88 is stirred, the extension that can realize gear 83 or gear 85 respectively closes, export thus realizing power by gear 84 or gear 86, it is achieved two are just kept off；Gear 81, gear 82 are in normal engagement, and gear 87 empty set is on axle, and engaging sleeve 89 is stirred to the right the extension that can realize gear 87 and closed, and exports power by gear 86 and makes output shaft reverse, thus realizing reversing gear。The power of change speed gear box 8 output drives cylinder 15 to rotate by shaft coupling 56, is hoisted tubing string by hook block 16。
Because when hoisting tubing string, the weight of tubing string is change, is being gradually reduced。In order to more make full use of engine energy, it is to avoid " low load with strong power " phenomenon existed on conventional workover rig, it is configured with three power gears。When hoisting little weight tubing string, adopt the little power gear of low-power machine 2 and little quantitative hydraulic pump or motor 3 composition, when hoisting medium wt tubing string, adopt the middle power gear of big engine 1 and big quantitative hydraulic pump or motor 4 composition, when hoisting big weight tubing string, adopt 1,2 and two quantitative hydraulic pumps of two engines or the gear energetically of motor 3,4 composition。So can realize " big horse traction cart, little horse traction dolly ", make full use of energy, save energy。
The work process of tubing string of hoisting under gear energetically is as follows。Clutch 61,62 all engages, and first two-bit triplet reversal valve 9 and second two-bit triplet reversal valve 10 are all placed in right position。During the less important work of the tubing string that hoists, clutch 63 separates, cylinder 15 is checked by roll brake 13, connection tooth on first engaging sleeve 73 and the second gear 74 is separated, second engaging sleeve 76 move right realization connect with the connection tooth on the 5th gear 77 and, engine 1,2 drives two quantitative hydraulic pumps or motor 3,4 to work in " pump " operating mode to oil-filled in hydraulic accumulator 12, stores energy。When hoisting tubing string, it is moved to the left the second engaging sleeve 76, making it be separated with the connection tooth on the 5th gear 77, move right the first engaging sleeve 73 so that it is engages with the connection tooth on the second gear 74, select suitable change speed gear box gear, clutch 63 engages, and unclamps roll brake 13, and the pressure oil in hydraulic accumulator 12 drives two quantitative hydraulic pumps or motor 3,4 to work in " motor " operating mode, drive cylinder 15 to rotate together with engine 1,2, hoisted tubing string by hook block 16。So the general power of engine 1,2 greatly reduces than conventional workover rig, it is only about the 1/4 of conventional workover rig。
Hoisting under little power gear, it is similar with the process of the tubing string that hoists under gear energetically to hoist tubing string under tubing string, middle power gear, simply hoist under little power gear tubing string time, all the time clutch 61 is separated, all the time second two-bit triplet reversal valve 10 is placed in left position；Hoist under middle power gear tubing string time, all the time clutch 62 is separated, all the time first two-bit triplet reversal valve 9 is placed in left position。
Hoist under a certain power gear tubing string time, when the tubing string weight hoisted is less, stirs engaging sleeve 88 and make gear 85 hang to close, gear 86 export power, namely with the high gear fast lifting of change speed gear box。When the tubing string weight hoisted is bigger, stirs engaging sleeve 88 and make gear 83 hang conjunction, gear 84 export power, namely hoist by the low gear of change speed gear box。
When transferring tubing string, the weight of tubing string is also change, is being gradually increased。The tubing string very light in weight transferred at the beginning, now two quantitative hydraulic pumps or motor not engaging work。Along with the increase transferring tubing string weight, by little quantitative hydraulic pump or motor 3 engaging work, under little power gear, the gravitional force discharged transferred by recovery tube post。When tubing string weight increases to a certain degree, by big quantitative hydraulic pump or motor 4 engaging work, under middle power gear, the gravitional force discharged transferred by recovery tube post。When tubing string weight is further added by a certain extent, two quantitative hydraulic pumps or motor 3,4 being simultaneously engaged with work, under gear energetically, the gravitional force discharged transferred by recovery tube post, and the gravitional force now reclaimed is maximum。
Now under gear energetically, transfer tubing string, concrete operating process is described。When transferring tubing string, engine 1, 2 shutdown, connection tooth on first engaging sleeve 73 and the second gear 74 is separated, connection tooth on second engaging sleeve 76 and the 5th gear 77 is separated, first two-bit triplet reversal valve 9 and second two-bit triplet reversal valve 10 are all placed in right position, select suitable change speed gear box gear, unclamp roll brake 13, tubing string under action of gravity own under put into well, make cylinder 15 rotate simultaneously, cylinder 15 rotate through change speed gear box 8, the clutch 63 engaged drives two quantitative hydraulic pumps or motor 3, 4 rotate simultaneously, now two quantitative hydraulic pumps or motor 3, 4 are operated in pump condition, in hydraulic accumulator 12 oil-filled, namely the gravitional force of tubing string is become the pressure in hydraulic accumulator 12 can store。This partially recycled energy can re-use, and completes the work during less important work with it, as completed to promote single operation, drives button, driving pressure mechanism of qi, it is provided that the energy etc. of controlled clutch and brake on tubing tongs。These work in the past are all completed by engine, now by having recovered energy, are greatly saved the energy。
Transfer under little power gear that to transfer tubing string under tubing string, middle power gear similar with the process transferring tubing string under gear energetically, when simply transferring tubing string under little power gear, all the time second two-bit triplet reversal valve 10 is placed in left position；When transferring tubing string under middle power gear, all the time first two-bit triplet reversal valve 9 is placed in left position。
When a certain power gear transfers tubing string, when the tubing string weight transferred is less, stirs engaging sleeve 88 and make gear 85 hang conjunction, gear 85 export power, namely transfer with the high gear of change speed gear box。When the tubing string weight transferred is bigger, stirs engaging sleeve 88 and make gear 83 hang conjunction, gear 83 export power, namely transfer by the low gear of change speed gear box。
